I seen Supras out there with like 900hp and they run 10 sec quater miles. Shouldn't they be getting faster times with horsepower like that. I seen Civic hatchback with 400 horspower run 11 and there Front wheel drive too.
Any one have a explanation for this?

I guess it just has bad differential?

Weight is the big drawback of the supras.

What do 300 hp, 400 hp, and 500 hp JZ's have in common?

12 second timeslips.

Call me Crankshaft

perhaps turbo spool is a factor?? most of those 900hp supras have sumthing like a t-88 im sure after they really get a chance to spool up they would be doing like 200mph or so
i would like to see a 900hp supra and a 400hp civic compete against eachother on the salts .. muhaha

I EAT RICE!

weight is the major issue and also most of them are 6spd . its tought o make 9 second passes on a 6spd. With a turbo400 tranny almost any 750+hp supra will go 9's.

95' RSP Supra 1000k+rwhp soon.

Traction is the major issue. It is hard to find the right traction set up. Trying to find the best suspention upgrade to hook the car up to run into the 9's. The power, mile an hour, is all there it is just getting the power to the road and hooking the car up so it doesn't spin the tires, or get squirrelly off the line. And another thing with the supras is the weight factor. They are pretty heavy, I think around 3400lbs with the driver. So weight and traction is the two major issues. Lag isn't much of an issue now a days with the new dual ball bearing turbos which have a wicked spool time and power curve.

Hey motormatrix, I see in your signature that you have a 95 RSP supra w/1000+rwhp in the works, is that factory paint or did you repaint it to that color?

I agree and disagree at the same time with everyone. I don't think it's weight that holds the supra down, even though it is a factor. Old School muscle cars weighed the same and sometimes more than a supra, if they pushed 700whp they would be runnin 9-8's.

The main thing is the power curve of the supra, a huge turbo does not help, a big block with a blower is ideal for a quarter mile lots of stump pulling torque and low end power to rip that heavy chassis off the line. The supra lacks the torque and the power curve to go as fast as muscle cars, IMO.

Second is definatly the traction, irs is not meant for drag, straight axel setup like on muscle cars allows them to pop wheelies and haul ass off the line, where we as supra owners are left standing, or should I say spinning.

The power curve, torque, and the irs are the things that kill the supra, in my opinion the main killer in slow supras which are sad to say are just poor drivers.

Also even though I love the 6spd getrag, it is not meant for drag. Don't get me wrong, it is beefy as hell and can handle tons of power, but even manual muscle cars were like 4 spd. They could do 60 plus in 1st gear, reducing shifts, not to mention many of them were autos. Every shift is good for about .5 to .6 seconds, that's a lot. An old school muscle car shifts maybe twice, how many do we shift, 3-4 times, that ads another second or so.

Most supra owners are young and inexperienced like myself and have not had all that experice to drive such a high horsepower cars, especially 6spd owners.

i totally agree with you straight6. i can testify to the shifting, although my GTO is an automatic, when i drop it into 2 i can easily hit 70 mph, when its in D it shifts to 3rd when i am going about 85-90 mph. this helps a lot with reducing quarter mile times. the higher power a car is i think less gears is better for the quarter mile. automatic is also better IMO as long as you have a shift kit its going to be harder to shift it as fast as an auto.

the straight axel setup is also a good point, i dont think i have ever seen a supra do a wheelie before and its not like i havent seen any that dont have enough power to do so. has anyone ever seen a supra do a wheelie before?

Craig Paisley has popped a few wheelies before... However wheelies are bad. The ideal situation in a RWD drag car is to have soft enough suspension to allow the car to tilt back and launch hard. However tilting the car back too much causes inefficiency due to the fact that the force generated from the tires isn't all going to accelerating the car. The more you tilt, the more amount of that force goes to keeping the car tilted.

i agree with you rs3LTcar, i guess i just got caught up in the "it looks cool" factor. dont know why i forgot it would be bad to do so....but i still think the supras dont run as nice of times as they should for the power they can put out

Yeah, I agree with you on that one. The arguement about bottom-end torque availbility can be easily made when you're running 800HP on a Supra. However there are ways to build boost off the line. Perhaps the reason so many Supras run slower times are because so many people lower their Supras. They would definitly play a big role. The gears are pretty short on our transmissions as was mentioned above. Also I bet that IRS plays a large role as well.

It isnt the engine. It is the entire setup, as eluded to above.

The 6 second Solars that are JZ powered jump out of the hole. Of course, all 6 second cars do.

yes but paisley has a solid rear setup

Powerhouse Racing's Supra pulled wheelies with the stock IRS setup.

not many people set supras up for drag! How many supras do you see at the track w/wrinkel walls? most have gauty rims and low prows...

There are alot of key factors in putting a supra down the track quicker than a 10 sec pass with 800+ hp. Driver, and Setup are to me the biggest key factors. It is possible to run quick times with stock suspension, look towards Matt Miller, I believe he's ran high 9's on stock springs. That being an example of a good driver. As for setup up. We'll Look towards Titan motorsports, MSP, Ryan Woon. All these cars have been refined and built for application. If anyone is serious about running quick times they have to build up to that type of application. It is possible to come to the track cut a 10's pass on drag radials and drive home. 9's, 8', etc are times posted by most cars that come in on a trailor. As for having no lowend torque, etc.. Two-steps can address that issue fairly well. Again you need the setup to get the car to hook. Research, and time are the easiest ways to find that quicker time at the track. Driving has got to be the biggest factor though.. Thats my 2 cents on the topic

its the way the cars setup, and most importantly, coming out of the whole - if you have a big turbo on your car, and you launch way under boost, your et's will be alot slower, lauching in healthy boost crucial (on the right tire that is)! its all on 2 things, the setup and the driver
